CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE FRONT BRAKE CHAMBER ON SOME 18,000 LB. AND 20,000 LB FRONT AXLE ASSEMBLIES IS TOO SMALL TO MEET STOPPING DISTANCE REQUIREMENTS.

FUEL INJECTION SYSTEM RECONFIGURATION TO COMPLY WITH ENGINE EMISSION STANDARDS CAUSE HIGHER ENGINE VIBRATION LEVELS WHICH LEAD TO EARLY WEAR AND COMPLETE FAILURE OF THE SECONDARY THROTTLE RETURN MECHANISM.
